Pentax DA 70mm f/2.4 Limited: APS-C's proven portrait prime.
At 26mm long and 147g, this lens barely registers on a Pentax body, yet the 6-element, 5-group optical design punches well above its physical weight. The 70mm focal length translates to a 105mm equivalent on APS-C, putting it squarely in short-telephoto portrait territory with a narrow 23° angle of view. HD multi-layer coating on the glass elements suppresses flare and ghosting, which matters for backlit portraits and contrasty natural light. The SP coating on the front element repels oil, dirt, and fingerprints, keeping it easy to maintain in the field.
Nine rounded aperture blades at f/2.4 produce smooth out-of-focus rendering that portrait shooters expect from a prime at this focal length. Full-time manual focus override means you can refine focus without switching modes, a practical feature when shooting subjects close to the 0.70m minimum focus distance. The 49mm filter thread keeps accessory costs low, and the MH-RF49 hood is included. For Pentax shooters who want a dedicated portrait prime that doesn't burden a day's kit, this lens has a decade of proven performance behind it.
Who It's For
Portrait photographers shooting on Pentax APS-C bodies get a 105mm-equivalent field of view and f/2.4 maximum aperture in a package that weighs only 147g. Travel photographers carrying a light kit will appreciate the 26mm length, which makes it one of the smallest primes available for the KAF mount. Landscape shooters working in strong light benefit from the HD coating's flare resistance at a 23° angle of view that isolates subjects cleanly. Street and documentary photographers will find the full-time manual focus override useful when autofocus precision needs a final nudge.

FAQ
- What's the equivalent focal length on a Pentax APS-C body?
- 105mm. That puts you in classic portrait territory - long enough to compress features without distortion, short enough to work in tight spaces.
- How close can you focus with this lens?
- 0.70m (27.56"). Practical for head-and-shoulders work, though at 0.12× magnification it won't do macro-style close-ups.
- Does it have autofocus?
- Yes, driven by the camera's screw drive motor. Full-time manual focus override lets you fine-tune focus without switching modes.
- What's the optical design?
- 6 elements in 5 groups. HD multi-layer coating on the glass suppresses flare and ghosting. The front element also has SP coating to repel oil, dirt, and fingerprints.
- How many aperture blades, and what's the bokeh like?
- Nine rounded blades at f/2.4 deliver smooth, creamy out-of-focus areas. Rounded diaphragm is standard for portrait primes at this price tier.
- What's the physical footprint?
- 26mm long, 147g, 63mm diameter. Barely noticeable on a Pentax body. Uses standard 49mm filters.
- Is image stabilization included?
- No. This is a fixed focal length prime with no IS. Pentax bodies with in-body stabilization will still provide shake correction.
